COOLING SYSTEM.

To all whom it may concern:

Be it known that I, WILLIA F. DOYLE, a

citizen of the United States, residing at Reedsburg, in the county of Sank and'State of IVisconsin, have invented new and useful Improvements in Cooling Systems, of which the following is a full, clear, concise, and

exact description, reference being had tothe accompanying drawing, forming a part of this specification.

My invention relates to cooling systems and particularly to systems for cooling the medium utilized in an internal combustion engine to cool the working parts thereof.

It is well known that as a liquid is volatilized heat is absorbed to such an extent that t a considerable cooling effect is obtained.

Itis one of the objects of my invention toprovide means for utilizing th s refrigerating effect to cool the water, air or other medium used in cooling the cylinders and "1t has I fore, to run the water from the jacket of the working parts .of an internal combustion engine. I

been the ordinarypractice, heretoengine cylinder through a radiator whereby the water becomes somewhat cooled before form its cooling function, often reaching a boiling point whereby serious injury may be caused to the engine and its working efficienc materially impaired, all of which is well nown. My invention removes the possibility of such deleterious results by providing means for cooling the water orgother medium to such an extent-that it will always be at a proper temperature to carry out its necessary function. i

It is a further object of my invention to provide an apparatus for cooling the engine cooling medium that is simple in structure, economical to manufacture, easy to install, readily repaired and cleaned, and efficient in operation. 1

In the following description and accompanying drawings I have disclosed one preferred embodiment of my invention, it being understood that numerous changes may be made in the form, construction and arrange- Specification of Letters Patent.

Like reference characters refer to like parts throughout the following description and the several figures of the drawings.

In the embodiment of my invention here shown as a preferred example, the intake manifold 10 of an ordinary internal combustion engine 11 is provided with an enlargement immediately above the carbure'ter 12, in the form of a casing 13 which is se- 'curedto the intake pipe 10 in any suitable manner as by the bolts and nuts 14:. The casing'13= is provided with a-cap 15 secured thereto as at 16 and connected to the intake pipe 10 as at 16. The casin 13 has a shoulder 17 on opposite sides 0 which are secured or formed integral therewith, bosses 18, externally screw-threaded to engage the internally screw-threaded members 19 which latter serve as bearings for the pipes 20 and 20 leading from and to the cylinder jackets. Suitable packing is provided as shown at 21. Vithin the casing 13 are arranged a number of parallel, long, narrow, thin walled cells 22, set close together. On each cell near the top is formed a pair of shoulders I tracted portion by the clip like member 22.

Arranged across the shoulders 23 of the cells 22, on either sideof the apparatus, is a distributing plate 24 having openings 25 therein which correspond with the open ends "of the cells 22. Secured to each distributing plate 24 by bolts 26 is a plate2-l having formed therein a bushing 24 adapted to form connection with the pipes 20, and 20. Thus it will be seen that the water from the pipe 20 (taking water as an example of the engine cooling medium) is adapted to pass through the cells 22, the structure of the distributing plates 24 preventing access to the interspaces.

In order that the water will not merely cross the cells but will circulate thoroughly therethrough I provide a bafile. To this end, the walls of the cells 22 are struck in, as shown at 27 (Fig.4) to such an extent that the struck in portions.

approximately meet and thus substantially divide the cell down the middle thereof.

The struck in portions do not, however, extend entirely from top to bottom of the cells, the point of'their termination being clearly shown in Fig. 2 at 27. 'Below this point the cell is open from end to end as shown in Fig. 5. It will be'seen, therefore, that,

' with this structure, as the water circulates under the force of the pump usually provided therefor, it will pass from the pipe 20 through the openings 25 into the cells 22 and because it cannot cross the cells owing to the bafile formed by the struck in portions it will necessarily flow downward to a point.

below the baflie, (i. e., to a point below 27, Fig. 2) where it can cross the cells, up the other side and out through the openings 25 to the pipe 20, as shown by the arrows in Fig. 2. Thus there is a complete and thorough circulation throughout the entire apparatus, the advantage of which is hereinafter mentioned. In order to drain the water when desired, I provide a pet cock 28 which, passing through the casing, is screwed into a manifold connecting the several cells.

It will be noted that the cells 22 and plates 24 form a structural unit which may be removed bodily and as a whole from the casing if it is desired to clean or repair the apparatus. This is accomplished by unscrewing the nuts 16 and 16 and removing the cap 10, and severing the connectionwith the pipes 20 and 20 and with the pet-cock 28, ,whereupon the structure may be lifted bodily from the casing.

The operation of the device is as follows:

The hot water is circulated under force of the pump through the cylinder jackets, pipe 20, cells 22 and pipe 20 as heretofore described. 'Gas from the carbureter is drawn upward through the intake pipe 10 which the gas is passing'this refrigerating or cooling process is extremely thorough and complete and the water accordingly returns to the cylinder jackets at a proper temperature to carry out its function of coolingthe engine. When the throttle is opened to attain higher speeds or to meet hilly, sandy or muddy road conditions, the engine, and consequently the Water, will become more and more heated. But inasmuch as, with the wider throttle, more gas is drawn through the intake manifold the refrigerating eflectwill be greaterand so the water is continuously returned to the jackets at a' proper temperature.

It isto be understood that the apparatus may be used either with or without the usual radiator and is adapted for use with any engine cooling medium that is capable of the necessary circulation, water being chosen merely as an example for the purposes of description.

In the modification illustrated in Figs. 69 inclusive, the structure is in general the same except that the apparatus is so arranged that the gas from the carbureter' passes through the cells and the water flows through the interspaces. The intake pipe 10 is provided with an enlarged portion as before in the form of a casing 40. Upper and lower caps 4 1 and 42 aresecured to the casing by any suitable means as at 43 and 44 and to the intake pipe 10 as at 45 and 46, the

caps 41 and 42 having openings therein corresponding to the pipe 10. The casing LO' has, on opposite sides thereof, shoulders 47 and 48 to which are secured or formed integral therewith, bushings 49 and 50 which engage the ends of the water pipes 20 and Within the casing 40 are arranged a- 20*. series of long, narrow, thin walled cells' 51 set close together and parallel as before, but open at the top and bottom. These cells 51 are secured to top and bottom tube plates 52 and 53 so that the cells form a part of the continuity of the intake pipe 10 and the interspaces are closed therefrom. The top tube plate 52 extends beyond the cells 51 to overlap and be secured to shoulders 55 and Lisfri 55 on the casing 40 by the screws 54. Around the cells 51 at the bottom, its lower edge flush with the lower edge of the tube plate 53, is arranged a thin band 56 which bears against'packing 57, the casing being water. The water,by necessity, flows downa ward, therefore, to beyond the point 58 (the extent of the baffle being clearly shown in Fig. 6). It then crosses, passes up the other side and out via the pipe 20 back to the cylinder jackets. The circulation through the apparatus is thus substantially similar to that before described except that in the present structure the water flows through the inter-spaces instead of through the cells. To drain the water when necessary I provide a pet-cock 59. The cells 51 and tube plates 52 and form a structural unit as before, which may be bodily removed from the casing for cleaning or repairs, it'being only necessary to remove the cap 41 and the screws 54. The operation is substantially similar to that already described except, as mentioned above, the gas passes upward through the cells and the water circulates thrpugh the interspaces as hereinbefore described.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
